+To host your images, {% data variables.product.product_name %} uses the [open-source project Camo](https://github.com/atmos/camo). Camo generates an anonymous URL proxy for each image which hides your browser details and related information from other users. The URL starts `https://<subdomain>.githubusercontent.com/`, with different subdomains depending on how you uploaded the image. 
 
 Anyone who receives your anonymized image URL, directly or indirectly, may view your image. To keep sensitive images private, restrict them to a private network or a server that requires authentication instead of using Camo.
